A professional Windows troubleshooting toolkit is very different from a collection of ordinary utilities. An IT engineer, system administrator, network administrator, computer technician, or advanced Windows user regularly needs tools capable of answering questions such as:

• Which devices are connected to this LAN?
• Which TCP ports are open on a server?
• What exact CPU, motherboard, RAM, or GPU is installed?
• Is the CPU overheating or thermal-throttling?
• Is a graphics-driver problem causing crashes?
• Which packets are entering and leaving an interface?
• How can I securely connect to a Linux server?
• How can I transfer files using SFTP?
• How can I establish or troubleshoot a VPN?
• How can I create one USB drive containing multiple Windows and recovery ISOs?

The Pro Tools collection shown in the screenshot brings together utilities addressing exactly these requirements.

The collection includes:

Advanced IP Scanner, Angry IP Scanner, Cinebench R23, CPU-Z, Display Driver Uninstaller (DDU), GPU-Z, gsudo, HWiNFO, HWMonitor, Mullvad VPN, Nmap, OpenVPN Connect, Proton VPN, PuTTY, Simplewall, Ventoy, WinSCP, WireGuard and Wireshark.

These programs should not be considered alternatives to one another. Most perform completely different functions and become substantially more useful when combined into a structured troubleshooting workflow.

1. Understanding the Pro Tools Categories

The tools can broadly be organized into the following areas.

This distinction is important.

For example, Advanced IP Scanner and Wireshark are both networking utilities, but their purposes are completely different. Advanced IP Scanner helps discover devices, while Wireshark analyzes packets traveling across network interfaces. Wireshark describes itself as a network protocol analyzer capable of capturing and interactively examining network traffic.

2. Advanced IP Scanner

Advanced IP Scanner is primarily intended for quick LAN discovery.

An administrator can scan an IP range such as:

192.168.1.1 – 192.168.1.254

and identify reachable systems.

It can be particularly useful when troubleshooting offices containing:

• Desktop computers
• Laptops
• Servers
• Network printers
• Wi-Fi access points
• IP cameras
• NAS devices
• Routers
• Managed switches
• Other network equipment

Practical Example

Suppose a network printer was previously configured as:

192.168.1.150

but users suddenly cannot print.

Instead of manually checking every possible address, an IP scanner can help discover currently reachable devices and identify the printer's present address.

Best suited for

Fast Windows LAN discovery where simplicity is more important than deep port/service analysis.

3. Angry IP Scanner

Angry IP Scanner provides a similar basic concept but is open source and cross-platform.

It supports Windows, Linux and macOS and can scan IP ranges and ports. It can also gather information such as hostnames and MAC addresses, with additional capabilities available through plugins.

Why IT administrators like it

It provides a convenient compromise between:

Simple graphical network discovery

and

more advanced command-line network scanning.

For routine inventory or troubleshooting, you may simply specify an address range and start scanning.

Advanced IP Scanner vs Angry IP Scanner

Advanced IP Scanner is particularly convenient in Windows-heavy environments.

Angry IP Scanner becomes attractive when the organization has:

Windows
Linux
macOS

systems because the same scanning utility can be used across platforms.

4. Nmap

Nmap takes network scanning considerably further.

While a simple IP scanner answers:

"Which systems appear to be online?"

Nmap can help answer:

"What network services are those systems exposing?"

It is widely used for network discovery, port scanning, service identification and authorized security auditing.

For example:

nmap 192.168.1.10

performs a basic scan of a host.

To scan a subnet:

nmap 192.168.1.0/24

Additional capabilities can include service detection, OS detection and more detailed network enumeration.

Important security consideration

Only perform scanning against networks and systems you own or are explicitly authorized to test.

Aggressive scanning against external infrastructure without permission can violate organizational policy, provider rules or applicable law.

5. Wireshark

Wireshark operates at another layer entirely.

Rather than merely identifying devices or open ports, it allows an administrator to inspect network packets.

The project describes Wireshark as a free and open-source network protocol analyzer capable of capturing and interactively browsing network traffic.

A capture can help investigate protocols including:

TCP
UDP
DNS
DHCP
HTTP
TLS
SMB
ICMP
ARP
SSH
and many others

Example: DNS troubleshooting

Suppose:

ping 8.8.8.8

works, but:

ping example.com

fails.

This strongly suggests investigating DNS.

Wireshark can show DNS queries and responses and help determine whether:

• DNS queries are being sent
• The correct DNS server is contacted
• Responses are received
• Queries time out
• Unexpected responses occur

Display filters

A major Wireshark capability is filtering.

For example:

dns

shows DNS traffic.

tcp

shows TCP packets.

icmp

shows ICMP traffic.

ip.addr == 192.168.1.10

focuses analysis on traffic involving a particular IP address.

Wireshark's documentation supports capture filters and display filters, making large captures much easier to investigate.

6. CPU-Z

CPU-Z is primarily a hardware-identification utility.

It is useful when you need exact information about components without physically opening the machine.

Typical information includes:

CPU

• Processor model
• Architecture
• Core information
• Clock frequency
• Cache information

Motherboard

• Manufacturer
• Model
• Chipset
• BIOS information

Memory

• Installed memory
• Memory type
• Frequency
• Timings
• SPD information

For computer technicians, CPU-Z is particularly useful during:

RAM upgrades, CPU verification, motherboard identification and hardware inventory.

7. GPU-Z

GPU-Z serves a similar purpose for graphics hardware.

It provides detailed GPU-related information such as:

• GPU model
• Graphics processor
• Memory
• BIOS information
• Bus interface
• Driver information
• Clock speeds
• Sensors

This is useful when diagnosing:

• Gaming performance problems
• Incorrect graphics drivers
• GPU overheating
• Laptop GPU configuration
• Used graphics cards
• Driver installation problems

8. HWiNFO

HWiNFO is one of the most comprehensive utilities in this collection.

It combines:

hardware identification + sensor monitoring + reporting.

HWiNFO describes its capabilities as comprehensive hardware analysis, real-time monitoring and reporting. It can monitor CPUs, GPUs, motherboards, drives and other components.

Typical monitored values include:

CPU temperature
CPU clocks
CPU power
GPU temperature
GPU clocks
Fan speeds
Voltages
Drive temperatures
Memory information
Thermal throttling indicators

Why HWiNFO is particularly useful

Suppose a laptop becomes slow after ten minutes of heavy use.

Task Manager may show high CPU utilization but does not necessarily explain why performance suddenly drops.

HWiNFO can help determine whether:

CPU temperature rises
        ↓
thermal limit reached
        ↓
CPU frequency decreases
        ↓
system performance drops

This makes it extremely useful for thermal and performance troubleshooting.

9. HWMonitor

HWMonitor is another hardware-monitoring utility.

It is commonly used for quickly viewing:

• CPU temperatures
• GPU temperatures
• Voltages
• Fan speeds
• Power readings
• Storage temperatures

Its straightforward interface makes it useful when an administrator needs a quick sensor overview without exploring the deeper hardware hierarchy available in HWiNFO.

HWiNFO vs HWMonitor

A practical distinction is:

HWMonitor → quick sensor checking

HWiNFO → detailed diagnostics, sensors, inventory, logging and reporting

There is substantial overlap, so many technicians do not need both running continuously.

10. Cinebench R23

Cinebench R23 is a CPU benchmarking utility.

It places a rendering workload on the processor and generates a performance score.

This can be useful for evaluating:

• CPU performance
• Cooling performance
• System stability
• Performance after upgrades
• Thermal throttling
• Differences between power profiles

Diagnostic workflow

A useful combination is:

Start HWiNFO sensor monitoring
        ↓
Run Cinebench R23
        ↓
Observe CPU temperature
        ↓
Observe CPU frequency
        ↓
Check thermal throttling
        ↓
Compare benchmark score

This provides considerably more information than simply looking at the benchmark number.

11. Display Driver Uninstaller (DDU)

Display Driver Uninstaller is commonly known as DDU.

Its purpose is to thoroughly remove graphics-driver components when normal uninstall/reinstallation is insufficient.

This can be useful when troubleshooting:

• Corrupted GPU drivers
• Black screens
• Driver installation failures
• GPU vendor changes
• Driver conflicts
• Repeated graphics crashes
• Incorrect driver remnants

Typical troubleshooting approach

A technician may use the following workflow:

Download the correct replacement GPU driver
        ↓
Disconnect unnecessary network access if appropriate
        ↓
Boot into Safe Mode when recommended
        ↓
Run DDU
        ↓
Remove old graphics-driver components
        ↓
Restart Windows
        ↓
Install the correct driver

DDU should generally be considered a troubleshooting tool, not something that needs to be run before every ordinary graphics-driver update.

12. gsudo

Linux administrators commonly use:

sudo

to execute commands with elevated privileges.

gsudo brings a similar workflow to Windows terminals.

It can be convenient for administrators who frequently work with:

Command Prompt
PowerShell
Windows Terminal
scripts
administrative commands

Instead of opening another elevated terminal manually, elevation can be requested from the command line.

Because elevated commands can modify protected areas of Windows, administrators should always verify commands before executing them.

13. PuTTY

PuTTY is a well-known remote terminal client.

Its most common modern use is SSH administration.

For example:

Windows workstation
        ↓ SSH
Linux server

Typical targets include:

• Linux web servers
• VPS systems
• Network appliances
• Firewalls
• Routers
• Switches
• NAS systems
• Embedded devices

PuTTY is especially useful for administrators managing Linux infrastructure from Windows.

14. WinSCP

WinSCP complements remote terminal administration by providing secure file-transfer functionality.

A common configuration is:

Protocol: SFTP
Host: server.example
Port: 22
Username: administrator
Authentication: password/key

WinSCP can also integrate with PuTTY, allowing an administrator to move conveniently between graphical file management and terminal administration.

Practical combination

PuTTY
   ↓
Command-line server administration

WinSCP
   ↓
Secure server file management

This is an extremely useful combination for Windows administrators managing Linux web servers.

15. OpenVPN Connect

OpenVPN Connect is a client for connecting to OpenVPN-based VPN infrastructure.

Organizations may use VPN connections to give remote users encrypted access to:

Office servers
Internal applications
File servers
RDP servers
ERP systems
Private web applications
Network resources

A configuration profile generally contains the information required to establish the encrypted VPN tunnel.

16. WireGuard

WireGuard is a modern VPN technology designed around a relatively compact architecture and cryptographic configuration.

A basic WireGuard configuration conceptually contains values such as:

Private Key
Public Key
Endpoint
Allowed IPs
Interface address

It is increasingly used for:

• Site-to-site connectivity
• Remote administration
• Cloud servers
• Private networks
• Secure remote access

OpenVPN vs WireGuard

Both can create secure VPN connections, but they use different architectures and configuration models.

OpenVPN has a long history and broad deployment ecosystem.

WireGuard is often attractive when simplicity, modern cryptography and lightweight operation are priorities.

17. Proton VPN

Proton VPN is primarily a consumer/business privacy VPN service rather than simply a generic VPN protocol client.

It can route Internet traffic through Proton VPN infrastructure.

Typical motivations include:

• Privacy on untrusted networks
• Encrypted VPN tunneling
• Changing Internet egress location
• Testing connectivity from another region

It should not be confused with a corporate VPN connecting directly into an organization's internal LAN.

18. Mullvad VPN

Mullvad VPN occupies a similar general category: a VPN service focused heavily on privacy.

For technicians, privacy VPN services can also be useful for testing whether a website or service behaves differently depending on:

• ISP
• Public IP address
• Geographic exit location
• Network routing

However, a commercial privacy VPN is not a substitute for properly configured enterprise remote-access infrastructure.

19. Simplewall

Simplewall provides Windows network filtering/control capabilities.

It can help administrators control which applications are permitted to communicate over the network.

This is useful for:

• Application network control
• Troubleshooting unexpected connections
• Privacy management
• Restricting unwanted outbound communication

Because firewall changes can break application connectivity, administrators should document changes and test them carefully.

20. Ventoy

Ventoy solves a completely different but extremely useful technician problem.

Traditionally, creating bootable USB media often involved repeatedly rewriting a USB drive for each ISO.

Ventoy enables a multiboot approach.

A technician can maintain a USB drive containing multiple ISO images such as:

Windows 11
Windows Server
Linux
Recovery environments
Hardware diagnostics
Approved rescue environments

At boot time, the desired image can be selected.

Why technicians benefit

Instead of carrying:

USB 1 → Windows installer
USB 2 → Linux
USB 3 → Recovery environment
USB 4 → Diagnostics

a properly prepared Ventoy drive can consolidate multiple boot images.

Always obtain operating-system and recovery images from legitimate, trusted sources.

21. How These Tools Work Together

The real value comes from combining tools.

Scenario 1: Unknown device on network

Use:

Advanced IP Scanner
        ↓
Identify active devices
        ↓
Nmap
        ↓
Inspect authorized device ports/services
        ↓
Wireshark
        ↓
Analyze relevant network traffic

Scenario 2: Computer overheating

Use:

CPU-Z
   ↓
Identify CPU/RAM/platform

HWiNFO
   ↓
Monitor temperatures and clocks

Cinebench R23
   ↓
Generate CPU load

HWiNFO
   ↓
Check throttling and temperature behavior

Scenario 3: Graphics-driver problem

Use:

GPU-Z
        ↓
Identify graphics hardware

HWiNFO
        ↓
Check GPU sensors

DDU
        ↓
Clean problematic driver installation when justified

Vendor driver
        ↓
Install correct driver

Scenario 4: Linux server administration

Use:

WireGuard/OpenVPN
        ↓
Establish authorized private connection

PuTTY
        ↓
SSH administration

WinSCP
        ↓
SFTP file management

Scenario 5: Network application not working

Use:

IP Scanner
        ↓
Is target reachable?

Nmap
        ↓
Is expected service reachable?

Wireshark
        ↓
What actually happens at packet level?

This layered troubleshooting methodology is much more effective than randomly changing Windows settings.

22. Recommended Technician Toolkit Structure

A professional toolkit can be organized as:

PRO-TOOLS
│
├── Hardware
│   ├── CPU-Z
│   ├── GPU-Z
│   ├── HWiNFO
│   └── HWMonitor
│
├── Benchmark
│   └── Cinebench
│
├── Network
│   ├── Advanced IP Scanner
│   ├── Angry IP Scanner
│   ├── Nmap
│   └── Wireshark
│
├── Remote
│   ├── PuTTY
│   └── WinSCP
│
├── VPN
│   ├── OpenVPN
│   ├── WireGuard
│   ├── Proton VPN
│   └── Mullvad
│
├── Drivers
│   └── DDU
│
├── Security
│   └── Simplewall
│
├── Administration
│   └── gsudo
│
└── Boot
    └── Ventoy

This makes a technician USB drive much easier to maintain.

23. Which Tools Are Most Important?

If only a small toolkit can be maintained, a strong general-purpose Windows support combination would be:

HWiNFO is particularly capable because it combines detailed hardware identification, monitoring and reporting rather than performing only one of those functions.

24. Portable vs Installed Tools

For technician use, portable applications can be extremely convenient.

Advantages include:

• No permanent installation
• Easy USB storage
• Faster deployment
• Less modification of customer systems
• Easier version management

However, some tools require installation, drivers or elevated privileges for their full functionality.

For example, packet capture on Windows normally requires an appropriate capture driver such as Npcap.

Therefore, "portable" does not automatically mean "zero system changes."

25. Security Precautions

Powerful diagnostic utilities should be treated carefully.

Download from trusted sources

Avoid random software-download websites, repackaged installers and unknown mirrors.

Whenever possible, obtain utilities from:

• Official developer websites
• Official project repositories
• Trusted package repositories

Verify digital signatures

For Windows executables:

Right-click → Properties → Digital Signatures

when a publisher provides signed binaries.

Keep tools updated

Network and security utilities may receive important fixes.

An outdated technician toolkit can itself become a security problem.

Do not scan unauthorized networks

Network scanners should only be used against systems you own, administer or have explicit authorization to test.

Protect VPN credentials

Private keys and VPN configuration files should not be casually stored on an unencrypted technician USB.

Protect packet captures

Wireshark captures can contain sensitive information including:

• IP addresses
• Hostnames
• Internal topology
• Protocol metadata
• Unencrypted application data

Treat PCAP/PCAPNG files as potentially confidential.

26. Tools That Overlap

Installing every tool is not mandatory.

There is overlap between:

CPU-Z and HWiNFO

CPU-Z provides convenient CPU/platform/RAM identification.

HWiNFO provides considerably broader hardware and sensor information.

HWMonitor and HWiNFO

Both monitor hardware sensors.

If HWiNFO satisfies your requirements, HWMonitor may be optional.

Advanced IP Scanner and Angry IP Scanner

Both are useful for fast network discovery.

You may prefer one according to platform and workflow.

Proton VPN and Mullvad VPN

These are primarily privacy VPN services. An administrator normally does not require both unless testing multiple VPN providers or exit networks.

OpenVPN and WireGuard

These are different VPN technologies. Which one you need depends on the remote infrastructure.

27. Suggested Workflow for IT Engineers

Instead of launching tools randomly, troubleshoot from broad symptoms toward detailed evidence.

Hardware problem

CPU-Z/GPU-Z
      ↓
HWiNFO
      ↓
Cinebench where appropriate
      ↓
Driver investigation
      ↓
DDU only when justified

Network problem

IP configuration
      ↓
Ping
      ↓
Advanced/Angry IP Scanner
      ↓
Nmap
      ↓
Wireshark

Remote server problem

Internet connectivity
      ↓
VPN
      ↓
Ping/DNS
      ↓
Nmap/service test
      ↓
PuTTY
      ↓
WinSCP

A structured approach reduces unnecessary changes and makes troubleshooting repeatable.
